… there was Hugo Gernsback. Here are a few of his contributions:
– Established one of the first companies to sell equipment to radio amateurs in 1904.
– Founded the Wireless Association of America in 1909.
– Published two amateur radio oriented magazines: Modern Electrics in 1908 and The Electrical Experimenter in 1913.
– Initially proposed the idea of allocating 200 meters and down to amateur radio in 1912.

Why don’t we know more about Hugo Gernsback and his early contributions to the hobby? At what point did the momentum shift from Hugo and his Wirless Association of America to Hiram Maxim and his ARRL? … and why?

Hugo made a huge contribution to science fiction but it seems his contributions to amateur radio have been overlooked.

My intent for this blog is to serve primarily as a notebook – a place where I can capture important details concerning my amateur radio activities and then refer back to them if needed. This includes interesting websites, hamshack successes and failures, equipment settings, as well as plans for the future. Occasionally the subject matter on the blog opens a bit broader… beyond amateur radio .

The cliche about some long time hams of having life “take over” at some point in a ham career is a cliche for a good reason. Sometimes the balance tips and radios are put on the backshelf. I’m at a mid-life career transition point, retiring from the military and moving into “the next phase”. Plan A is to become an elementary school teacher. None of my previous academic work really supports this transition and despite popular misconceptions, in the state of Kansas… you can’t just show up and say “Hey, I’d like to be a teacher!” It is actually a somewhat difficult process. Fortunately a nearby university has a well respected program that I am not too far from completing. The program is time intensive (this semester I am taking 13 credit hours… while working full-time). This is my last semester behind the desk. I start my retirement transition at the end of December and in January I start student teaching.

One of the great aspects to the program I am in is that I get plenty of time inside elementary grade classrooms so I have a clear idea of what I am getting into. Over the last 12 months I have had the opportunities to visit numerous classrooms seeing various grade levels and teaching styles. It is great going into this transition with my eyes wide open.

However, this educational experience (along with work) has been time-intensive. My time in front of the radio (or submitting blog entries) has been seriously limited. The hamshack has become somewhat of a dumping ground (for my other hobbies of O gauge model trains and 80′s arcade games) and only recently was I able to did a path out from the door to the operating desk. My goal is to adjust the balance just a bit and spend a little more time with the radios. We’ll see how it goes.

“Getting the Message Through: A Branch History of the U.S. Army Signal Corps” by Rebecca Robbins Raines
CENTER OF MILITARY HISTORY, UNITED STATES ARMY, WASHINGTON, D.C., 1996 (pgs 242-244)

During 1940 President Roosevelt had transferred the Pacific Fleet from bases on the West Coast of the United States to Pearl Harbor on the Hawaiian island of Oahu, hoping that its presence might act as a deterrent upon Japanese ambitions. Yet the move also made the fleet more vulnerable. Despite Oahu’s strategic importance, the air warning system on the island had not become fully operational by December 1941. The Signal Corps had provided SCR-270 and 271 radar sets earlier in the year, but the construction of fixed sites had been delayed, and radar protection was limited to six mobile stations operating on a part-time basis to test the equipment and train the crews. Though aware of the dangers of war, the Army and Navy commanders on Oahu, Lt. Gen. Walter C. Short and Admiral Husband E. Kimmel, did not anticipate that Pearl Harbor would be the target; a Japanese strike against American bases in the Philippines appeared more probable. In Hawaii, sabotage and subversive acts by Japanese inhabitants seemed to pose more immediate threats, and precautions were taken. The Japanese-American population of Hawaii proved, however, to be overwhelmingly loyal to the United States.

Because the Signal Corps’ plans to modernize its strategic communications during the previous decade had been stymied, the Army had only a limited ability to communicate with the garrison in Hawaii. In 1930 the Corps had moved WAR’s transmitter to Fort Myer, Virginia, and had constructed a building to house its new, high-frequency equipment. Four years later it added a new diamond antenna, which enabled faster transmission. But in 1939, when the Corps wished to further expand its facilities at Fort Myer to include a rhombic antenna for point-to-point communication with Seattle, it ran into difficulty. The post commander, Col. George S. Patton, Jr., objected to the Signal Corps’ plans. The new antenna would encroach upon the turf he used as a polo field and the radio towers would obstruct the view. Patton held his ground and prevented the Signal Corps from installing the new equipment. At the same time, the Navy was about to abandon its Arlington radio station located adjacent to Fort Myer and offered it to the Army. Patton, wishing instead to use the Navy’s buildings to house his enlisted personnel, opposed the station’s transfer. As a result of the controversy, the Navy withdrew its offer and the Signal Corps lost the opportunity to improve its facilities.

Though a seemingly minor bureaucratic battle, the situation had serious con­sequences two years later. Early in the afternoon of 6 December 1941, the Signal Intelligence Service began receiving a long dispatch in fourteen parts from Tokyo addressed to the Japanese embassy in Washington. The Japanese deliberately delayed sending the final portion of the message until the next day, in which they announced that the Japanese government would sever diplomatic relations with the United States effective at one o’clock that afternoon. At that hour, it would be early morning in Pearl Harbor.

Upon receiving the decoded message on the morning of 7 December, Chief of Staff Marshall recognized its importance. Although he could have called Short directly, Marshall did not do so because the scrambler telephone was not considered secure. Instead, he decided to send a written message through the War Department Message Center. Unfortunately, the center’s radio encountered heavy static and could not get through to Honolulu. Expanded facilities at Fort Myer could perhaps have eliminated this problem. The signal officer on duty, Lt. Col. Edward F French, therefore sent the message via commercial telegraph to San Francisco, where it was relayed by radio to the RCA office in Honolulu. That office had installed a teletype connection with Fort Shafter, but the teletypewriter was not yet functional. An RCA messenger was carrying the news to Fort Shafter by motorcycle when Japanese bombs began falling; a huge traffic jam developed because of the attack, and General Short did not receive the message until that afternoon.

Halloween is just around the corner. It is far and away one of my favorite holidays and I am looking forward to spending it with my family this year. Beyond the Trick-or-Treating, costumes, Halloween decorations, and pumpkin carving, I like telling my two young daughters ghost stories. This got me to thinking if there were any stories out there that had to do with both amateur radio and Halloween. And sure enough, there are.

So now its time to dim the lights…..

The first story is by Brian, N4TRB, and was inspired by an October 1932 article he read in QST by Don Mix. Brian’s story is called Whisky November Papa: A Tale for Halloween and is worth a read.

The next story was discovered by Dan, KB6NU, and is called Haunted Ham Radio. It is more amusing than scary, but still worth the read for a chuckle or two.

For those of my ham radio brethren who will be out and about on Halloween helping provide communications for a safe and sane holiday – I salute you! And if you are in my neighborhood this year, stop by for some Trick-or-Treat, pumpkin pie, and hot apple cider… and maybe a quick tour of the hamshack.

The story of the Elser-Mathes Cup may be familiar to many of you. For those of you who are not in the know, you can get all the details from the article by Fred Johnson Elser, W6FB/W70X, in the November 1969 issue of QST. To summarize, the establishment of the Elser-Mathes Cup in 1929 was directly inspired by the leaps and bounds up to that point in radio technology combined with Hiram Percey Maxim’s fascination with the planet Mars. The cup is to be awarded in recognition of the first amateur radio two-way communication between Earth and Mars. I would bet that the cup’s initial establishment was somewhat tongue-in-cheek. Although Fred Johnson Elser’s QST article, on the tail of the success of Apollo 11, gave the cups existence and purpose a good deal more veracity.

How close are we to finally awarding the Elser-Mathes Cup? Lets look at some recent milestones:

Earth-Moon-Earth Bounce
In January 1953, Ross Bateman, W4AO, and Bill Smith, W3GKP successfully bounced at 2M signal off the Moon.

Signal reception of Voyager 1

On March 31, 2006, German radio amateurs successfully received transmissions from Voyager 1 which was already well outside the Solar System (~7,436,464,581 miles away from Earth).

Earth-Venus-Earth Bounce

On March 25, 2009, German radio amateurs achieved another first by bouncing a 2.4 GHz CW signal off of Venus – which at its closest point to Earth is a mere 24,000,000 miles away and 162,000,000 miles at its furthest.

Earth-Mars-Earth Bounce?
Mike Brink, ZR6BRI, has definitely done his homework to show the feasibility of radio amateurs bouncing a signal off of Mars (which has a distance from Earth that varies from 36,000,000 miles to 250,000,000 miles).

However, bouncing a signal off of Mars will not win The Elser-Mathes Cup. The amateur contact must be two-way.

Could the Mars Science Labratory (Curiosity) fulfill the role as the second party of an amateur QSO?

Curisoity does have UHF communication capability. One of Curiosity’s antennas is nicknamed “Big Mouth” and is used to send large data sets to one of three orbiters around Mars: the Mars Reconnaissance Orbiter (which will probably do most of the work), Mars Odyssey Orbiter, or the European Space Agency’s Mars Express orbiter. The orbiter then relays the data via the Deep Space Network (DSN) back on Earth using X-Band.

“Big Ear” is Curiosity’s high-gain, directional X-Band antenna that can be used to communicate directly with the DSN on Earth. “Little Ear” is an omni-directional, X-Band antenna that is designed to be used primarily to receive low data rate transmissions from the DSN.

Putting aside the fact that Curiosity’s X-Band frequencies are outside the authorized US amateur frequency allocation and given the German amateurs success with Voyager and Venus – amateur communication with Curiosity looks possible (but probably not with my Arrow II antenna).

So, if it is possible for Joe Amateur (along with a heap load of expensive gear) to have a QSO with Curiosity – what would prevent the actual hacking of Curiosity?

Damon Poeter’s August 9th article “How to Hack NASA’s Curiosity Mars Rover” takes a look at this proposition. Mr. Poeter all but dismisses the possibility of a private citizen contacting Curoisty and instead focuses at actually hacking through NASA’s control system. Then on August 10th, Mr. Poeter submits “Unknown Actor Soliciting Partners for Mars Rover Hack”. Now, possibily, there are individuals who are actually trying to hack their way through NASA by soliciting help in determining what frequencies are used to communicate with the orbiters above Mars.

Here on an IT secuirty forum, a question is asked concerning the secuirty of Curiosity. One of the responses is from a former controller who is somewhat familiar with NASA’s general communications protocal with spacecraft and identifies the transmission of bogus communications to Curiosity as a possibility. Although the post’s author identifies that the capability to conduct such an act would have to be another country (…. and everyone loves pointing the finger at China).

It is easy to forget that radio amateurs have been intercepting space communications for sometime, with Sputnik’s signal on 20.007 MHz and Apollo 11 communications being primary examples.

All this being said, I think The Elser-Mathes Cup will continue to gather dust for a bit longer.
